I try to be honest. When I attack I do so with the intention of placing tori on the mat, skill of the tori accepted. If the attack is jodan tsuki, then that's what they get and I try to ensure that I'm ready to attack immediately after tsuki (or whatever the attack is) is thrown, as I would if I were sparing or fighting. After that it's tori's job to place me on my behind and mine to ensure I don't get hurt as it would be for real. Some people often need help throwing me, so I usually help them out, it's dishonest but it has to be done.
